Russian scientists plan to make more gene editing babies Another scientist is seeking official approval for exemption from punishment His plan to make gene editing babies has shocked the scientific community Denis rebrikov, a Russian molecular biologist, said he plans to make a gene editor baby, according to the international top academic journal Nature on June 10 If the plan is implemented, he will become the second person to complete the work publicly in the world It is worth noting that, according to a report by Russian satellite news agency on October 29, 2018, before the publication of the world's first gene editing baby, rebrikov has used crispr-cas9 gene editing system to modify the embryo at the stage of fertilized egg Rebrikov's target gene is CCR5, which Targets AIDS As a member of GPCR, CCR5 gene is one of the main acceptors for HIV-1 to invade cells In some people with CCR5 homozygous mutation, the homozygous mutation can block the invasion of HIV In order to reduce the possibility of punishment for the experiment, rebrikov plans to first seek approval from three government agencies, including the Ministry of health It could take a month to two years, he said Https:// 56 people were successfully selected into the first batch of Tsinghua University's "scholars of waterwood" program in January 2019, and Tsinghua University's "scholars of waterwood" program officially launched the global recruitment This is another important measure for Tsinghua University to cultivate outstanding young scholars It plans to closely focus on the path and growth law of young scholars and devote itself to cultivating a group of outstanding young scholars who are dedicated to learning, brave in innovation, with a strong sense of social responsibility and international vision In May 2019, 56 outstanding talents at home and abroad were successfully selected into the first batch of Tsinghua University "Shuimu scholars" program through individual application, selection and recommendation of Colleges (departments, institutes), expert review and other procedures There are 20 overseas candidates, all from world famous universities, including Harvard University, Cambridge University, Princeton University, University of Chicago, Columbia University, UCLA, University of Pennsylvania, University of Michigan and other world top universities, including 5 foreigners 32 domestic candidates are from "double first-class" construction universities Four postdoctoral researchers were selected Http://news.tsinghua.edu.cn/publish/thuneews/10303/2019/20190611112154096491603/20190611112154096491603/20190611112154096491603.html expansion leads to the shortage of dormitory beds? Dr Yanbi of Nanjing University was "rushed" to the undergraduate dormitory, which caused a "delayed doctoral student" dormitory adjustment storm due to the shortage of dormitory, making Nanjing University get attention again Recently, the dormitory of South University Xianlin Campus posted a notice on the arrangement and adjustment of student dormitory in summer 2019 The doctoral student who has been postponed for more than one year will be adjusted by the school to arrange accommodation, and the accommodation standard will be adjusted to 4 persons / rooms from the previous 2 persons / rooms As soon as the news came out, most of the delayed doctoral students in South China were questioned and dissatisfied According to the delayed doctoral students, the dormitory conditions and management mode of undergraduate students are not suitable for the work and rest time of doctoral students, and most of the delayed doctoral students are in the critical period of writing papers and looking for jobs "Suddenly changing dormitory" will bring pressure and anxiety such as moving, adapting to the new environment, and running in interpersonal relationships At present, it is not clear the number of doctoral students delayed by the dormitory adjustment However, according to student estimates, according to the delay rate of more than 50%, there may be more than 1000 doctoral students delayed by the University HTTPS: / / baijiahao Baidu COM / S?
